yup aptasia and hydroids. kill with fire and kill with superglue and putty, respectivelty.

 

[justingraham]

So quick google of hydroids shows they are bad so what's so bad about them and ur saying put putty over them? I already shot the aptasia with aptasia x

 

[justingraham]

And what are the worm looking things?

And what are the worm looking things?

mini brittle stars

what's so bad about them

they sting HARD corals and fish. and they spread.

 

[justingraham]

Got ya can they move like aptasia ? Or they stuck there?

Got ya can they move like aptasia ? Or they stuck there?

stuck. I believe they bore into the rock and also send "spores"

 

[justingraham]

And the spores are on the glass of the aquarium?

 

[Tahoe61]

The Brittle Stars are harmless and a common hitch-hiker. They are broadcast spawners and can move freely around the tank.

Nice score btw. Lotta life on that rock. Keep an eye out for any strange.

And the spores are on the glass of the aquarium?

I think they get spit into the water, so they may be seen on the glass but IME no.

DO you know how the hydroids spread?. I thought they did the same.

I wish my brittles would spawn more.:(

Well the only weird thing is I got this rock from my buddy and I know for a fact cause I was there when he bought the rock 5 years ago that it was just rock it wasn't live so if he didn't introduce anything how is the rock this literally alive?

 

[justingraham]

And any strange? I'm on a cliff waiting for what comes next

[justingraham]

And thanks guys

Colonial Hydroids like those in the image use budding.

My Brittle Stars spawn if I do a water change where the alk value is the make up water is a higher value then the display water. Hard to say if that is related to pH or not. Tanks with few or no hermits have higher populations of brittle stars and stomatella.

 

[justingraham]

Man U know ur hitch hikers

 

[Tahoe61]

Hydroids, Stomatella, Brittle Stars, Aiptasia, Flatworms, Red Bugs, Byropsis, Asterina Stars, coral eating Nudibranch can all be introduced to a system on frags. That is why it's so important to inspect pieces prior to purchase and dip, although not all dips treat or kill all hitch-hikers.

I have like 100 of these guys in here like this in fact two in this picture and they are all ok?

Those are Bristle worms. As long as they don't get too big, or too many they are good. Well, if you ask 10 people about them, you might get several different answers!
